Homemade Scarfer

homemade plywood scarfer Cut a piece of particle board 24" inches by 16" inches. Glue a 2x4 to one 24" inch edge. Now angle the edge so a 7-1/4" inch saw bolted onto that angled edge almost but not quite cuts all the way through 1/2" plywood. For an 8-1/4" saw you can set to cut all the way through.

Here's the not obvious part: You have to be super careful and precise when mounting the saw. You want the saw absolutely dead parallel or you might even want to mount the saw ever so slightly not parallel so the front, leading edge of the blade is dead flush to the particle board edge while the rear tailing edge of the blade perhaps 1/5th the width of the blade away from the particle board.

If the saw ends up mounted not parallel to the particle board, so the leading edge of the blade is not dead flush the saw will gradually migrate downward as you cut, and eventually it will bind.

To scarf two four foot plywood edges together--to make a longer panel--put the plywood down on a firm flat surface a few feet up from the floor. Clamp a straight edge approximately 16" inches back (trial and error will give the exact measurment, which you can then remember) from the edge you want to cut. Now run the saw with the particle board foot pressed tightly against the straight edge. The massive weight of all that particle board keeps the saw from shaking. With a freshly sharpened blade you'll get a baby smooth cut.

This is a 7-1/4" inch saw, which are the most common. An 8-1/4" saw is a bit better suited. I recently hacked an old 8-1/4" inch saw so it takes a 10" blade. The longer the blade the longer the scarf. And the longer the scarf the stronger the scarf.

Belt Sander

Belt sander finally got useful. I need to rebuild the frame so I can sand curved parts with the front end of the sander. Today was a tool building day. Scarfer comes next. Belt sander got useful

Cardboard deck rim

:=))
I might have to replace it with plywood and fiberglass. We'll see. This (the cardboard pattern) is the outer rim of a two or maybe three part deck. The inner deck section(s) will bolt down onto the perimeter rim over a 1" inch thick foam gasket, so wave crashing can't swamp the boat and sink it.
The whole inner section(s) will hinge up and down (in one or maybe two parts) so you can store coolers and camping gear below, without having to fight with a rabbit warren of hatch covers that are never big enough. Most of the visible cross braces shown here are only temporary. Progress happens. Slowly.
